Gmail API

Theory

101/268

Gmail API sends mail with smtplib / email.message, or a Gmail API. You need host, port, login. Never hard-code passwords in source — use env vars.

Classroom: show the Message structure (From, To, Subject, body). Real send needs credentials; the example prints the message text so it always runs.

Output — three header lines. Gmail API sends the same fields with OAuth — not a password in code.

Exam tip

Parts of an email + never commit passwords.

# Gmail API
print("From: teacher@school.in")
print("To: asha@school.in")
print("Subject: Marks")

Output: three header lines. Gmail API sends the same fields with OAuth — not a password in code.
